To all whom it may. concern:

.Be it known thatI, PETER J PAULY, Jr., citizen of the United States,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Door- In the drawings, Figure 1 is a top plan ofa corridor door, showing lever-box in horizontal section; Fig. 2 is avertical section on broken line 22 of Fig. 1; Fig; 3 is an enlargedhorizontal section on the line 3'3 of Fig. 2 Fig. 4 is a perspective ofthe operating handle or lever and parts immediately con trolled thereby;Fig. 5 is a vertical section on the line 55 of Fig. 4 Fig. 6 is an innerface view of a portion of the gravity or drop-bar; Fig. 7 is an enlargedsectional detail on line I 77 of Fig. 2; Figs. 8, 9fand 10 areelevational views illustrating three successive stages of operation ofthe arresting pin for the drop-bar, and of the locking bolt controllingthe corridor-door; Fig. 11 is a horizontal section on the line 1111 ofFig. 10; and Fig. 12 is a detail section on the line 12-12 of Fig. 10. UI

The present invention has special application in connection withcorridor jail doors, and has for its object to provide means against anypossible unlocking of such door, even though the prisoner shouldaccidentally gain access-to the lever box or compartment in which thevarious operating levers for controlling the door, are located.

The invention finds particular application in the case of doors providedwith gravity locking-b ars which engage the bolts by which the door islocked or secured when closed, such bars requiring a longitudinalshifting to disengage them from the bolts referred to. Since theretraction of the locking-bolts and the shifting of the bar is generallyeffected by the same lever operating successively in two distinctdirections,' it is impossible to maintain the bar in suchdisengagedposition for the purpose of retracting the bolts unless someprovision be made to temporarily hold the bar in its shifted ordisengaged position after the lever has been' swung in proper directionto effect the disengagement. In my invention this temporary retention orarrest of the gravity bar can be accomplished only through the releaseof a spring-bolt or pin by the retraction therefrom of a spring-latchunlocked by a key in possession only of the keeper, so that he alone canshift the gravitybar to and retain the same in, proper position topermit the retraction of the bolts by which the corridor door is locked.The pin is automatically restored to re-ngagement with its latch uponthe final closing of the door which is thus dead-locked, all as willhereinafter more fully appear from a detailed description of theinvention which is as follows Referring to the drawings, D represents ahinged door opening into the jail corridor G from the passage P in frontof the cells A, the free edge of the door being provided with a strikeor keener K which on ages the ends of the locking-bolts B protrudingthrough the side wall of the lever compartment or box L in which theoperating levers are housed, the box beingclosed by a door D as wellknown in theart. The bolts B here shown are three in number, the top andbottom ones bein provided with the ejecting sprin s 1, 1, coile aboutthebolts, and confined etween the supportin angle brackets 2, 2, throughwhich theiolts are free to slide, and collars 3, formed on the bolts. Atan intermediate point the several bolts are connected with a plate 4which is braced at the bottom by a triangular plate 5. When the door I)is locked the ends of the bolts are concealed by an angle bar 6 securedto the free edge of the door in front of the keeper or strike K. Theseveral features described are well known and form no part of thepresent invention. The rear ends of the several locking bolts 13 operateloosely in the adjacent leg of an ang e bar 7 in front of the inner faceof which reciprooates vertically the locking gravity or drop-bar 8 whichis guided in its movements by pins 9 passing through elongated openings0 in the bar, othero enings o of a similar character being provi ed toallow for the free passage therethrough of the several bolts B. When thelocking-bar 8 is in its lowest position the portions thereof immediatelyabove the openings 0 settle in or engage suitable recesses r formedalong the upper walls of the bolts 13, said engagement preventing theretraction of the bolts inwardly and hence preventing theirwithhorizontal plane, one arm of which is coupled to the adjacent end ofa horizontal link 13 whose opposite end is pivotally secured to one armof a bell-crank lever 14 oscillating in a vertical plane, and pivoted tothe rear wall of the box L. The free end of the opposite arm of thebell-crank 14 is provided with a laterally projecting pin 15 w iichbears against the under side of a pin 16 projecting from the drop-bar 8.The outer arm of the bell-crank lever 12 is loosely coupled to a link 17whose forward end is pivotally secured to the disk 20at the base of abent operating le ver 18 rovided with a stud 19 rotatably mounte in theplate 11. It will be seen from the connections described, that byswinging the lever 18 inwardly (plain arrow Fig. 4) through a sufficientangle, the bellcrank 12 will be oscillated in proper direction to pushthe link 13, which in turn will rock the bell-crank 14 in properdirection to cause the pin 15 to lift the pin 16 and hence raise the bar8 sufficiently to effect its disengagement from the bolts B. The boltsbeing disengaged are now free to be retracted or forced inwardly out ofen agement with their keeper K. This is accomplished as follows :At thebase of the operating handle or lever 18 is a disk 20 at the top ofwhich is formed a curved slot 21 through which operates a pin 22projecting from the face of a reciprocating bar 23, the latter beingsupported by pins 2 1 secured to the plate 11 and operating throughelongated slots 25, 25, in said reciprocating bar. To an inner terminalbracket 26 of said bar is pivotally secured one arm of a horizontallyoscillating bellcrank lever 27 pivoted to a bracket 28 which is rivetedto the plate 11. The opposite arm of the bell-crank 27 is pivotallycoupled to the adjacent bracket 29 of a push-bar 30 whose opposite endis secured to the plate 4 connected to the series of bolts B.

The bolts B being as above stated, disengaged from the drop-bar 8, if wenow oscillate the handle 18 outwardly as per feathered arrow in Fig. 1,(or in a direction opposite to that for effecting a raising of thedrop-bar 8) the end wall of the slot 21 will push against the pin 22thus forcin the bar 23 inwardly, whereby the bell-cran r 27 will beoscillated in proper direction to bear against the pushbar 30, thelatter in turn pushing against the plate 1} to which it is secured, andhence retracting or withdrawing the entire series of bolts B away fromin front of their keeper K, and allowing the door D to be swung open andrelease the prisoners into the corridor. (if course, in order that thebolts l5 may be retracted, the drop-bar 8 must be kept in its raisedposition until the recesses r have passed the danger of the barreengaging the same in the retracting movement of the bolts; for it isobvious that when the handle 18 is reversed to retract the bolts B it atthe same time releases the drop-bar 8 (which had been raised with theinward movement of the handle). It therefore follows that some provisionmust be made after the bar has been raised, to hold the same upten'iporarily, or long enough to permit the recesses r of the bolts topass beyond the path of the bar and thereby prevent the bolts from beinglocked before their retracting movement can begin. This temporaryarresting device. for the dropbar, to hold the same out of engagementwith the bolts B (to which position it was lifted by the inward strokeof the lever v18) until after their retracting movement has begun is oneof the important features of the present invention, and consists of thefollowing mechanism :Secured to the rear wall of the lever be L at apoint below the middle bolt B, is a lock 31. operated by a key 32 whichretracts or actuates a spring latch 33, normally forced out b y a spring(not shown) this being a form of lock well known in the art andrequiring no detailed description. Below the lock casing is secured abracket 3 1 between whose terminal ears 0, c, is loosely mounted a pinor bolt 35 having any outer terminal rounded head 36 located exterior-1yto one of the ears 0, the base of which head the latch engages for aretracted position of the pin (Figs. 8, 1.0). The pin is provided with acollar 37, between which and the ad jacent car a is located a coiledexpanding spring 38 which tends to drive the pin t0- ward thegravity-bar 8 and in fact does so when the latch 33 is retracted by thekey 32.

When the jailer has oscillated the operating lever or handle 18 inwardlyto raise the gravity-bar 8, he at the same time with one hand appliesthe key 32, turning it to disengage the latch 33 from the head 36,whcreupon the pin 35 being released is forced toward the gravity-bar 8,the latter being provided at the proper point with an opening I: toreceive the end of the pin 35 which thus arrests the bar 8 against areturn movcn'ient after being once raised to release the bolts B (Fig.9). The bar 8 thus temporarily arrested, permits the operator to newswing the lever 18 in the opposite or outward direction to effectretraction of the bolts as already explained, for purposes of freeingthe keeper K of the door D, and allowing the latter to open. \Vith theretracting or in lit) by the operator causes the bevel end of the latchto spring in front of the head 36 (Fig.

9). Now, the middle bolt B is provided on the side with a air of pinsp,19, between which is disposed the upper arm of a releasing lever 39pivoted to the box Wall, the lower arm terminating in a forked end whichspans the pin 35 behind the collar 37. After the bolts have beenretracted or forced ini ward 'sufiiciently to bring' the recesses 1(Fig. 10-), the outer pin 2 strikes the lever 39 osci-llatingit inproper direction 'to cause its forked end to pressagainst the collar 37and force the in 35 back to'its original position, the roun ed surfaceof the head 36 forcing the latch 33 inwardlyuntil the latter slips offthe edge of such rounded surface and again automatically drops backbehind the flat base of thehead (Fig. 10). Of course, upon release ofthe lever 18 after the full retraction of the bolts and the opening ofthe door D, the bolts spring back to their outward position under theaction of their ejecting springs 11, 1, allowing the gravity-bar 8(released from the arresting pin as described) to 5 again drop back intoengagement with its recesses r of the bolts, the parts being restored tooriginal position (Fig. 3). viously the door D (if opened) can not beslammed shut, since the bolts'are again looked against movement, but tolock the door, the operatorsimply imparts with one hand an inwardoscillation or stroke to thelever 18 which raises the bar 8 todisengaging position, and with the other hand applies the key 32 to thelatch 33 retractingthe latter from behind the head 36 of the pin 35,allow ing the latter to snap into engagement with the gravity-bar. Thebolts being now free from their locking bar 8, the door may be slammedagainst the outer protruding ends of the bolts, the keeper K drivingthem in-, wardly (a movement corresponding to the retracting movement ofthe bolts for purposes of opening thedoor) in which inward movement thepin 35 is released (as in Fig.

10), thus freeing the gravity bar 8,'which, after the bolts have sprungoutwardly in front of the keeper on the complete closing of the door,drops back into its recesses r on the bolts, and the door is dead-locked(Fig. 8). And should the lever-boX door .D be left open accidentally,the prisoner could not open the corridor door D even though he could getaccess to the lever 18, because the bar 8 will not stay up to allowthe'bolts B to be retracted unless temporarily held up by the pin 35,which can only be released by the key 32 in the pocket of the jailer.Should "the prisoner succeed in oscillating the lever i 18 suiiicientlyto raise the bar 8, the momenfl, he swung the lever in the oppositedirection to retract or push in the bolts, the bar would instantly fallback into its notches or recesses r on the bolts, and the latter couldnot be moved. It therefore requires a key, or some equivalent means torelease the arresting-pin by which the gravity bar may be temporarilyheld up until the bolts'are re- 1 tracted to permit thecorridor door toopen.

. Of course, the principle can be applied to any door, and is notrestricted to corridor doors. Having described my invention,'what I'fclaim is:

1. In combination with a sliding lockingbolt, a gravity or drop barnormally engaging the bolt against movement, means for.
